Documents show that slain Navy SEAL and “American Sniper” Chris Kyle received fewer medals for his military service than what he indicated in his best-selling memoir about his four tours of duty in Iraq.

Navy files show that Kyle earned one Silver Star and three Bronze Stars with valor, instead of the two Silver Stars and five Bronze Stars his book says he received.

The documents were obtained by the online magazine The Intercept through an open-records request, and the Navy on Wednesday confirmed the contents of the documents to the Associated Press.

The Silver Star is the third-highest military combat decoration. The Bronze Star is awarded to members of the armed forces for heroic or meritorious achievement or service in a combat zone.

Lt. Jackie Pau, a Navy spokeswoman, told the AP that Kyle’s military personnel file states he received one Silver Star and three Bronze Stars with valor.

Kyle’s discharge paperwork, known as a DD214 form, indicated he had received two Silver Stars and at least five Bronze Stars, which is what he wrote in his book.

“The Navy considers the individual service member’s official military personnel file and our central official awards records to be the authoritative sources for verifying entitlement to decorations and awards,” Pau said in a statement.

Kyle, regarded as the deadliest sniper in US history, was fatally shot at a Texas shooting range in 2013.

His book was later made into a hit movie in 2014, with Bradley Cooper portraying Kyle.
